to append text to "/root/.profile"

I want to append some text to a privileged file /root/.profile. I used following scripts to do so.

sudo echo "blabla" >> /root/.profile

it still complains with permission denied. What is the right way to do so? I am using bash4 on ubuntu12.04

Yes the shell will open /root/.profile before running sudo. You need something like:

echo 'blabla' | sudo tee -a /root/.profile

The stream redirect >> is evalutated before sudo is even called. The simple answer is to put the whole thing inside a sub-shell:

sudo sh -c "echo 'blabla' >> /root/.profile"
